Definitions
- the present invention relates to substituted dibenzo[b,y]pyrido[l,2-d]oxazepine-2-amines and dibenzo[£,/Jpyrido[l,2-J]thiazepine-2-amines that are modulators of progesterone receptors, to their application in the field of contraception, hormone replacement therapy (HRT) or therapy of gynaecological disorders, as well as adjuvant therapy in cancer and other diseases, and to methods for the making and use of such compounds.
- HRT hormone replacement therapy
- gynaecological disorders as well as adjuvant therapy in cancer and other diseases
- Intracellular receptors are a class of structurally related proteins involved in the regulation of gene transcription. Steroid receptors are a subset of these receptors, including the progesterone receptor (PR), androgen receptor (AR), estrogen receptor (ER), glucocorticoid receptor (GR) and mineralocorticoid receptor (MR). Regulation of a gene requires the intracellular receptor and a corresponding ligand which has the ability to selectively bind to the receptor in a way that affects gene transcription.
- PR progesterone receptor
- AR androgen receptor
- ER estrogen receptor
- GR glucocorticoid receptor
- MR mineralocorticoid receptor
- Progesterone receptor modulators are known to play an important role in the health of women.
- the natural ligand for PR is the steroid hormone progesterone, but synthetic compounds have been made which may also serve as ligands (see e.g. Jones et al., U.S. Patent No. 5688810).
- Progestagens are currently widely used for hormonal contraception and in HRT. Other important clinical applications of progestagens are treatment of gynaecological disorders (e.g. endometriosis, dysmenorrhea, dysfunctional uterine bleeding, severe premenstrual syndrome), breast cancer, hot flushes and mood disorders, and luteal support during IVF. In addition, they are applied in combination with other hormones and/or other therapies including, without limitation, chemotherapeutic agents such as cytotoxic and cytostatic agents, immunological modifiers such as interferons and interleukins, growth hormones or other cytokines, hormone therapies, surgery and radiation therapy.
- chemotherapeutic agents such as cytotoxic and cytostatic agents
- immunological modifiers such as interferons and interleukins
- growth hormones or other cytokines hormone therapies, surgery and radiation therapy.
- steroidal progestagens have been proven to be quite safe and are well tolerated. Sometimes, however, side effects (e.g. breast tenderness, headaches, depression, and weight gain) have been reported that are attributed to these steroidal progestagens, either alone or in combination with estrogenic compounds. In addition, steroidal ligands for one receptor often show cross- reactivity with other steroidal receptors. Many steroidal progestagens also bind e.g. to the androgen receptor, whereas many antiprogestagens have affinity for the glucocorticoid receptor.
- Non-steroidal progestagens have no structural similarity with steroids and therefore might be expected to display differential behaviour with respect to physicochemical properties, pharmacokinetic (PK) parameters, or tissue distribution (e.g. CNS versus peripheral), and, more importantly, may show no or less cross-reactivity to other steroid receptors. Therefore, non- steroidal progestagens may be expected to score differently on these aspects and thus offer advantages over steroidal progestagens when applied in therapy.
- PK pharmacokinetic
- [l,4]tmazepine-2- amines are known e.g. from DE 2420168.
- the compounds mentioned there are described as having activity on the central nervous system, especially anti-depressant activity.
- [l,4]diazepine-2-arnines where the 2-amino group bears an acyl or alkylsulfonyl substituent are described in WO 2006/084917. These compounds are claimed to have agonistic, partial agonistic or antagonistic activity towards the glucocorticoid receptor.

- [l,4]oxazepine-l- amine, dibenzo[6,/]pyrido[ 1 ,2-d ⁇ [ 1 ,4]thiazepine- 1 -amine, dibenzo[b,/]pyrido[ 1 ,2-d] [ 1 ,4]diazepine- 1 -amine or dibenzo[c,/]pyrido[l,2- ⁇ ]azepine-l-amine have been described as non-steroidal progesterone receptor modulators with affinity for the progesterone receptor (WO 03/084963).
- Progestagenic activity is described for members of all four subclasses, i.e. the oxazepine, thiazepine, diazepine and azepine subclass. It is therefore very remarkable and highly unexpected that the compounds of the present invention, being dibenzo[b,/Jpyrido[l,2-c?][l,4]oxazepine-2- amines and dibenzo[b,/Jpyrido[l,2-J][l,4]thiazepine-2-amines, differ markedly from the dibenzo[£j]pyrido[l,2- ⁇

- Progesterone receptor-B activity and glucocorticoid activity in a transactivation are Progesterone receptor-B activity and glucocorticoid activity in a transactivation.

- the EC50 is often employed, the EC50 being the concentration of the compound being studied where the effect for a certain activity is half (50 %) of the maximum effect that can be reached for said activity.
- the EC50 is 10 "7 or lower; more preferably, the EC50 is 10 " or lower; most preferably, the EC50 is 10 " or lower.
- the glucucorticoid activity of a compound of the invention (EC50 and intrinsic activity) was determined in an in vitro bioassay of CHO cells stably transfected with the human glucocorticoid receptor expression plasmid and with a reporter plasmid in which the MMTV-promoter is linked to the luciferase reporter gene.
- the bioassay with the cell line known under the name CHO-GR B4.8, is performed analogous to the bio-assay with the cell-line CHO-PRB-pMMTV-LUC 1E2-A2 as described in Dijkema et al. (1998) J. Steroid Biochem. MoI. Biol. 64:147-56.

- the selectivity of one activity over another activity for a compound can be determined by comparison of the difference of the two activities concerned. For such a comparison, the ratio of the two EC50s concerned is frequently employed.
- the selectivity is a factor of ten (that is, the concentration at which the 50 % level is reached for one activity is ten times higher than the concentration of the same compound at which the 50 % level is reached for a second activity; in such a case, the compound is said to be selective for the latter activity) or higher; more preferably, the selectivity is a factor of one hundred or higher; most preferably, the selectivity is a factor of one thousand or higher.
- the compounds of the subject invention showed selectivity in their activity towards the progesterone and glucocorticoid receptors.
- the activity of the compounds of the subject invention towards the progesterone receptor was considerably higher than the activity towards the glucocorticoid receptor; thus, as outlined in the definition given before, the concentration of a compound of the subject invention at which a progestagenic effect is produced is much lower than the concentration at which the same compound produces a glucocorticoid effect.
